Accept the fact that you embody "gentrification" and that the whole point of you getting a big financial leg up on this is that you are not a hoodlum, you are not the sort who yells outside other peoples' windows and that, demographically speaking, they have a lot more to fear from you, white man, than you have to fear from them.

Also, you have expressed an intention (combined with, I believe, a contractual obligation) to live there for a good long while so considering your passion for volunteering, the sooner you start integrating yourself into the community, getting involved in the beautification, raising the funds, and adding to the renovation the happier you will be. Strangers yelling outside your window at the middle of the night? Potential confrontation. Bob's kids yelling outside your window at the middle of the night? You can tell them to keep it down in clear conscience. FWIW: even confronting strangers isn't hard. Our corner in LA was heavily frequented by college kids in need of Ubers and standing on the balcony and saying "Ladies, I hate to be 'that guy' but I got a 6am call and a toddler that sleeps light so if you could keep it down a little it'd be a blessing" was remarkably effective. Meanwhile up here our neighbor has a basketball hoop pointed to the street and stepping out onto the porch in a bathrobe to say "guys, seriously? It's 1am" gets them to scatter shamefaced. Really, so long as you can keep your conversation out of the realm of "keep it down you damn kids" you'll probably be fine.
